Venom chemistry of ants in the genusMonomorium
Journal of Chemical Ecology, 1982A comparative analysis of the venomous alkaloids produced by ant species in the subgenusMonomorium of the genusMonomorium has been undertaken. All species produce mixtures of unsymmetricaltrans-2,5-dialkylpyrrolidines, but the proportions of the constituents may vary considerably between species.

Fractionation of bulldog ant venom
Toxicon, 1974Abstract The venom of an Australian Bulldog Ant, Myrmecia pyriformis, has been fractionated by means of low voltage starch gel electrophoresis and gel filtration on Sephadex G50 and G75 columns. The aims of the study were (a) to establish whether the biological activities which had previously been described resided in separate venom components, and ...

Kinins in ant venoms—A comparison with venoms of related hymenoptera
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 19891. Venom preparations have been made of six ant, one pompilid wasp, two mutillid wasp, and four social wasp species. 2. The venoms were analysed pharmacologically in order to detect kinin-like activity. 3. Due to the small amounts of venoms available only a cascade of smooth muscle preparation could be used. 4.

A Harvester Ant Venom: Chemistry and Pharmacology
Science, 1978The mammalian toxicity of the potently algogenic venom of the ant Pogonomyrmex badius is greater than that reported for any other insect venom. This enzyme-rich venom contains high concentrations of phospholipase A 2 and B, hyaluronidase, acid phosphatase, lipase, and esterases.

Prevention of anaphylaxis with ant venom immunotherapy
Current Opinion in Allergy and Clinical Immunology, 2003Worldwide, eight genera of ants have been associated with sting allergy. Until recently only whole ant body extracts have been used for immunotherapy. The purpose of this review is to examine recent advances in the understanding of ant venom allergy and treatment using venom immunotherapy.Public health problems due to severe ant sting anaphylaxis are ...

Current Opinion in Allergy & Clinical Immunology, 2010
The review summarizes knowledge about ants that are known to sting humans and their venoms.Fire ants and Chinese needle ants are showing additional spread of range. Fire ants are now important in much of Asia. Venom allergens have been characterized and studied for fire ants and jack jumper ants.

Chemistry of venom alkaloids in the ant genusMegalomyrmex
Journal of Chemical Ecology, 1991Chemical analyses of three species in the Neotropical ant genusMegalomyrmex have identified this taxon as the third myrmicine genus to produce alkaloids as major venom products. Workers ofM. leoninus and workers and ergatoids ofM. goeldii produce one or more of fourtrans-2,5-dialkylpyrrolidines previously identified in other myrmicine genera.M ...

Hypersensitivity to Fire Ant Venom
Annals of Allergy, Asthma & Immunology, 1996Reading this article will reinforce the reader's knowledge of the taxonomy, origin, and distribution of fire ants and will increase his ability to diagnose and manage reactions caused by the two imported species, Solenopsis invicta and richteri. This review will also enhance the reader's knowledge of the available diagnostic methods and therapeutic ...

The chemistry of fire ant venom
Tetrahedron, 1971Abstract Five alkaloids, three trans-2-methyl-6-alkylpiperidines, and two unsaturated analogues, have been identified in the venom of the red form of the fire ant, Solenopsis saevissima. The compounds are represented by the structural formulae I–V. Each has been prepared synthetically.
